Wind generated 6.6% of the world’s electricity in 2021. The large-scale turbines generally rotate at about 20 rpm. General Electric’s Haliade-X has a rotor diameter of 220 m. There are three blades each with a mass of 50,000 kg. Calculate its moment of inertia. What is the linear velocity and the angular velocity during standard operating conditions? How many rotations will the Haliade-X undergo in a 10-minute time span? A broken bearing causes a deceleration of the turbine at a rate of 0.7 rad/s2. How long will it take the turbine to stop rotating?

Three children are riding on the edge of a merry-go-round that has a mass of 105 kg and a radius of 1.50 m. The merry-go-round is spinning at 18.0 rpm. The children have masses of 22.0, 28.0, and 33.0 kg. If the 28.0 kg child moves to the center of the merry-go-round, what is the new angular velocity in revolutions per minute? Ignore friction, and assume that the merry-go-round can be treated as a solid disk and the children as point masses.

A propeller is modeled as five identical uniform rods extending radially from its axis. The length and mass of each rod are 0.829 m and 2.71 kg, respectively. When the propellor rotates at 589 rpm (revolutions per minute), what is its rotational kinetic energy ??
A merry-go-round is a common piece of playground equipment. A 5 m diameter (that's diameter) merry-go-round rotates frictionlessly. It has a mass of 166 kg and is spinning at 22 rpm (that's revolutions/minute... you will want to convert to radians/sec). John runs tangent to the merry-go-round at 2.5 m/s in the same direction that it is turning. John's mass is 27 kg. He then jumps onto the MGR and sits halfway between the outer edge and the center. (A)What is the initial angular momentum, LJ, of John? (B)What is the total initial angular momentum of the system? (C)Use Conservation of Angular Momentum to find the final angular speed of the merry-go-round?

Three children are riding on the edge of a merry-go-round that is 122 kg, has a 1.60 m radius, and is spinning at 15.3 rpm. The children have masses of 19.9, 28.5, and 36.8 kg. If the child who has a mass of 28.5 kg moves to the center of the merry-go-round, what is the new angular velocity in rpm? rpm t.
A child with mass 42 kg sits on the edge of a merry-go-round at a distance of 3.0 m from its axis of rotation. The merry-go-round accelerates from rest up to 0.40 rev/s in 10 s. a. What is the angular acceleration of the merry-go-round? Express this in radians/second. b. What is the angular velocity at 5 s? c. Calculate the centripetal acceleration and tangential acceleration at 5 s. d. What is the total acceleration at 5 s? e. If the coefficient of static friction between the child and the surface of the merry-go-round is 0.6, does the child fall off before 5 s? Hint: To determine this, calculate the frictional force and force due to the acceleration of the merry-go-round on the child. Compare the two forces to find which is larger than the other, therefore overcomes the other.
